Definitions
- the invention relates to a shrink chuck with tool cooling according to the preamble of claim 1.
- Shrink-fit chucks are known from WO 2010/022875 AI, in which a storage and collecting space for a coolant supplied by means of coolant channels are arranged in the front part of the shrinkage chuck within the receiving opening.
- the storage and collecting space is separated by a ring land from the free end face of the shrink chuck, wherein between the ring land and a clamped tool, an annular gap is present.
- These shrink chucks are designed in such a way that the coolant supplied via the coolant channels to the accumulation and collecting chamber exits only through the annular gap to the front of the tool to form a closed coolant jacket around the tool.
- the coolant is guided here substantially along the tool shaft and the possibilities of beam guidance to the tool are limited.
- the object of the invention is to provide a shrink chuck of the type mentioned, which is inexpensive to produce and still allows optimal cooling of the tools.
- the inner diameter of the annular web delimiting the storage and collecting space to the front is adapted to the inner diameter of the receiving opening such that, if possible, there is no annular gap between the annular web and the tool shaft.
- a coolant can be conducted in a simple and effective manner without coolant loss to the outlet openings provided in the annular web, and from there can be directed to the areas to be cooled.
- Ideally should no annular gap between the annular web and the tool shank exist, so that the entire coolant exits through the Auslassöff.
- the cross-section of the annular gap should be less than 20% of the total cross section of the outlet openings.
- the inner diameter of the annular web correspond to the inner diameter of the dividendöff ung.
- the annular web is formed by a arranged at the front end of the receiving body and fixedly connected to this cover.
- the cover plates can with outlet openings of various shapes to the different requirements, e.g. the length and diameter of the tools to be adjusted. Due to an inseparable connection of the receiving body with the cover plate, a permanent fixation with a correspondingly low failure probability of the connection is additionally provided.
- the annular web can also be designed in one piece with the receiving body.
- Precise positioning of the cover disc can be achieved by inserting it into a corresponding depression on the front side of the base body.
- the cover plate is welded to the receiving body, resulting in a stable and good sealing connection.
- the outlet ports may be formed by slots, slots, bores and the like or by a combination thereof.
- the outlet openings may also be designed to allow the escape of coolant at various angles relative to the shrink chuck. This can be achieved, for example, in that the outlet openings designed as bores have different angles with respect to the center axis of the shrinkage chuck. As a result, a targeted beam guidance on certain parts of the tool and / or the workpiece is possible.
- the one or moredeffenzuFINattie may be formed as a bore within the receiving body or as longitudinal grooves on the inner circumference of the receiving opening.
- the outlet openings are offset relative to thedeschzu GmbHkanälen in the circumferential direction of the receiving body partially or completely against each other. This allows an optimal storage effect within the storage and collecting space and a more uniform distribution of the coolant can be achieved on the outlet openings.
- Figure 1 shows a first embodiment of a shrink chuck in a perspective
- FIG. 2 shows the shrinkage chuck of FIG. 1 in a longitudinal section
- FIG. 3 shows a cover disk of the shrinkage chuck of FIG. 1 in a front view
- Figure 4 is an enlarged detail view Y of Figure 2;
- Figure 6 is an enlarged detail view X of Figure 5;
- Figure 7 shows a second embodiment of a cover plate in a front view and 8 shows a third embodiment of a cover plate in a front view and in sectional views.
- Figure 1 shows a shrink chuck 1 with a receiving body 2, which contains a receiving opening 3 for a tool shank of a tool.
- a receiving body 2 which contains a receiving opening 3 for a tool shank of a tool.
- cover plate 4 At the front end of the receiving body 2 with the receiving body 2 inextricably connected cover plate 4 is arranged with a plurality of slit-shaped outlet openings 5.
- a plurality of circumferentially spaced radial bores 6 are further provided for the supply of a coolant.
- the receiving body 2 has in the front region of the receiving opening 3 a storage and collecting space 7 designed as an annular groove.
- the cover plate 4 forms an inwardly projecting annular web 8, which limits the storage and collecting space 7 to the front and the tool shank out.
- the inner diameter of the annular web 8 corresponds to the inner diameter of the receiving opening 3, so that there is no annular gap between the annular web 8 and the tool shank after the shrinking of the tool.
- the cover plate 4 is inserted into a recess 9 at the front of the receiving body 2 and is e.g. undetachably connected by welding to the receiving body 2.
- the cover plate 2 the deformation of the receiving body 2 in the required for shrinking of the tool in the receiving body 2 heating and cooling join in accordance and also the ring land 8 can get as far as possible after installation of the tool to the tool shank after shrinking the tool.
- the coolant supplied to the storage and collecting space 7 is to exit via the slot-shaped outlet openings 5 and not via an annular gap between the annular web 8 and the tool shank.
- bores extending in the longitudinal direction within the receiving body 2 are arranged as coolant supply passages 10, which extend from the radial bores 6 as far as the storage and collecting space 7.
- a coolant in the storage and collecting space 7 and from there via the slot-shaped outlet openings 5 are directed to a tensioned in the receiving body 2 tool.
- the outlet openings 5 extend in the form of longer and narrow slits in the annular web 8 formed by the cover plate 4 from the inner circumference in the radial direction radially outward.
- FIG. 5 shows a receiving body 2 of a further exemplary embodiment of a shrinkage chuck according to the invention.
- the coolant supply channels 10 are formed as longitudinal grooves on the inner circumference of the receiving opening 3.
- the coolant supply ducts 10 designed as longitudinal grooves extend from a rear extended region 11 of the receiving opening 3 to the storage and collecting space 7. The coolant is also guided here through the coolant supply ducts 10 to the storage and collecting space 7.
- FIG. 6 shows that a recess 9 for receiving a cover disk 4 is also provided there on the front side of the receiving body 2.
- the storage and collecting space 7 may have a plurality of stages with different diameters in order to achieve an optimal storage and collecting effect and thus a uniform distribution of the coolant flow to the outlet openings 5.
- the coolant supply ducts 10 designed as longitudinal grooves continue to some extent also into the storage and collecting space 7, whereby likewise a favorable distribution of the coolant flow is achieved.
- FIGS. 7 and 8 show further embodiments of cover disks 4 with outlet openings 5 of different shapes.
- T-shaped slots are shown extending radially outwardly from the inner circumference.
- FIG. 8 shows a plurality of bores arranged in circular patterns, which have different angles with respect to the center axis of the cover disk 4. As a result, different areas of the tool can be cooled specifically. It will be appreciated that the shape, number, size and orientation of the outlet ports can be used to tailor the coolant supply to the tool to a variety of requirements. The invention is not limited to those described above and illustrated in the drawings
